Perhaps you should try some spelling variations:
sach ky » sac ky, sach ty, sach kem
luc van » luoc van, luu van, duc van
cam luc » cam xuc, cau luc
hieu va » lieu va, hieu qua
cua tre » cua te, cuu tre, cua triet
nang xa » lang xa, nang ma, mang xa
va cam » va cham, va cac, va cao
ban de » ban den, van de, ban ve
de cua » le cua, te cua, dieu cua

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sach y)) ((nang xa) OR (nang x)) hoi. hieu va cam luc van ban de cua tre~.
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) or (sach y)) ((nang xa) or (nang x)) hoi. hieu va cam luc van ban de cua tre*.
